SQL SERVER – Insert Data From One Table to Another Table – INSERT INTO SELECT – SELECT INTO TABLE

Following three questions are many times asked on this blog.

How to insert data from one table to another table efficiently?
How to insert data from one table using where condition to another table?
How can I stop using cursor to move data from one table to another table?

There are two different ways to implement inserting data from one table to another table. I strongly suggest to use either of the methods over the cursor. Performance of following two methods is far superior over the cursor. I prefer to use Method 1 always as I works in all the cases.

Method 1 : INSERT INTO SELECT
This method is used when the table is already created in the database earlier and the data is to be inserted into this table from another table. If columns listed in insert clause and select clause are same, they are not required to list them. I always list them for readability and scalability purpose.

USE AdventureWorks
GO
----Create testable
CREATE TABLE TestTable (FirstName VARCHAR(100), LastName VARCHAR(100))
----INSERT INTO TestTable using SELECT
INSERT INTO TestTable (FirstName, LastName)
SELECT FirstName, LastName
FROM Person.Contact
WHERE EmailPromotion = 2
----Verify that Data in TestTable
SELECT FirstName, LastName
FROM TestTable
----Clean Up Database
DROP TABLE TestTable
GO



Method 2 : SELECT INTO
This method is used when the table is not created earlier and needs to be created when data from one table is to be inserted into the newly created table from another table. The new table is created with the same data types as selected columns.

USE AdventureWorks
GO
----Create a new table and insert into table using SELECT INSERT
SELECT FirstName, LastName
INTO TestTable
FROM Person.Contact
WHERE EmailPromotion = 2
----Verify that Data in TestTable
SELECT FirstName, LastName
FROM TestTable
----Clean Up Database
DROP TABLE TestTable
GO



Both of the above method works with database temporary tables (global, local). If you want to insert multiple rows using only one insert statement refer article SQL SERVER – Insert Multiple Records Using One Insert Statement – Use of UNION ALL.

  • I use this code :
    INSERT INTO
    TableIzlez ([BrojNaSmetka],[Artikal],[Sifra],[Kolicina],[Cena_P],[Cena_N],[Prodavac],
    [Datum],[Fiskalna],[MasaBroj],[Oddel],[Zatvorena],[PodGrupa],[Cena_Produkti],[TipNaSmetka],[DDV],[Den])
    SELECT
    BrojNaSmetka,Artikal,Sifra,Kolicina,Cena_P,Cena_N,Prodavac,Datum,
    Fiskalna,MasaBroj,Oddel,Zatvorena,PodGrupa,Cena_Produkti,TipNaSmetka,DDV,’19.04.2018′
    FROM TableIzlezDneven

    After this code I delete the records from TableIzlezDneven ( DELETE FROM TableIzlezDneven) , and next day I use some code to fill the TableIzlez

    but sometimes on TableIzlez show double records from TableIzlezDneven .
    Why ?
